For the first, the initial value is found by finding y when x=0
When x=0
y=4 so the initial value is 4, making your answer
B. 4

For the second one take any two points and do y2-y1/x2-x1
We'll use points 0,0 and 1,3
3-0= 3
1-0=1
So the equation is 3/1x and there's no y intercept
So your answer is
D. y=3x

The speed of the motor boat is 62mph
So your answer is
A.62 miles per hour

The fixed amount is the same as the y intercept, so when x is 0
Y is 8
So your answer is B.$8
